The article discusses potentially mutually beneficial and cost-effective projects that can be implemented jointly by Mongolia and Russia in the field of infrastructure. Some major projects, such as the construction of a northern corridor connecting Russia and China through Mongolia, were planned as part of the “One Belt, One Road” project, which was agreed upon by the leaders of the PRC, Mongolia and the Russian Federation in 2016 in the city of Tashkent. The northern corridor includes three railway lines and two highways. The implementation of the projects will help expand economic and trade cooperation not only between Mongolia and Russia, but also between Asia and Europe, and ways to accelerate it are proposed. The importance of laying a  gas pipeline from Russia to China through Mongolian territory is emphasized.

Purpose. Development of an energy-intensive complex technology for processing tea leaves and obtaining new types of tea, which simplifies tea technology and expands the range of products.

Materials and methods. Physicochemical methods of analysis were used. For the quantitative and qualitative determination of mineral elements, a plasma atomic emission spectrophotometer icpe-9820 (Shimadzu, Japan) was used.

Results. Based on the developed technology, new types of liquid and granulated tea were obtained. The resulting green and black liquid teas are rich in catechins, which have antioxidant properties and P vitamin activity. Recipes have been developed for the preparation of carbonated and non-carbonated drinks, balms, low-alcohol drinks and prophylactic syrup from liquid green and black tea.

Conclusions. The developed technology is unique in that for the first time in world practice in the tea industry, two products were simultaneously obtained from tea leaves: liquid and granulated tea. Recommendations are given for the preparation and use of products based on liquid green and black tea.

The article considers an example of expanding the area of interest of the project to the sphere of pre-project activities aimed at solving the tasks of business planning and forming the concept of the future product. The main objective of the study is to review current and propose effective approaches to project business planning in the National Park—Development Region system.

To develop an effective, sustainable ecosystem of national park business models that make a positive contribution to the regional gross product (RGP) of the region, the current approaches to assessing the contribution of economic and other activities, including project activities, to the socio-economic development of regions and the country as a whole were analyzed. The analysis uses methodological recommendations for the development and adjustment of development strategies, as well as national indicators of socio-economic, sustainable, low-carbon development, climate change adaptation of the region’s economy. As a result of application of the considered approaches to business planning of the project in the system ‘National Park — Development Region’ a  list of measures to increase the investment attractiveness of the national park was developed. All activities are successfully compatible with the main objectives of the national park, such as preservation of biodiversity and cultural values (code) of the region. Business models are proposed for the effective contribution of national parks to the socio-economic development of the development region, taking into account the natural-resource and recreational potential of the park, interests of the local population, participants of internal and external tourism.

The sustainable ecosystem of business models for national park development considered in this article is not limited to the framework of a unique study for one region. The super task of this study was to create a prototype for sustainable socio-economic development of regions that include a network of regional protected areas and national parks.

Purpose. Maintaining approaches to designing a system for planned training of system integrator employees in relation to corporate infrastructure.

Methods. The company’s internal processes related to employee training are considered, approaches to designing a  system of planned corporate training for employees in the field of the department’s technological infrastructure are proposed.

Results. The need to develop our own system for planned corporate training of system integrator employees was substantiated, functional requirements were formed, the architecture of the software complex was designed, intersystem interaction was designed, algorithms for calculating user recommendations were proposed.

Conclusions. Despite the availability of solutions for corporate training on the market, developing your own system is still the optimal solution for a large company, allowing you to satisfy all the needs of employees and managers in managing corporate training, as well as the most optimal way to integrate the system into the existing over many years, the company’s technological infrastructure, while avoiding the involvement of thirdparty specialists.

Relevance. Currently, the labor market faces the pressing need to find suitable candidates. Over the past 5 years, the IT market has changed significantly. Due to the outflow and new ways to stimulate employment, it has become more difficult for companies to select qualified personnel to perform the necessary tasks.

Purpose. Using randomized systems of iterated functions to analyze the job seekers’ market and select the most suitable candidates for a given profile from the field of information technology.

Materials and methods. The data collected from open sources were used. The analysis was carried out using randomized systems of iterated functions. In the work, the cluster analysis method was used, typical representatives of each class were selected, and randomized systems of iterated functions were used to construct fractal sets.

Results. Three groups of candidates with different characteristics were formed. Conclusions. The use of randomized systems of iterated functions allows you to effectively analyze the labor market. The proposed approach improves the quality of candidate selection.

Introduction. The efficiency, reliability and scalability of a  communication network largely depend on the choices made by the routing algorithm. This is especially true now, due to frequent escalations of military conflicts, the consequences of which can affect the stability and reliability of network communications.

Purpose. Formalization of an algorithm that ensures fault tolerance of a communication network by constructing optimal routing.

Methods. Mathematical modeling, as well as experimental testing of the presented model based on various geodata through the practical implementation of a formalized algorithm.

Results. A mathematical model of the algorithm is proposed, which is based on algorithms for constructing a minimum spanning tree, as well as an example of its implementation.

Conclusions. The presented algorithm allows you to build routing that ensures fault tolerance of the communication network, in conditions of theoretical destruction of nodes in communication networks by determining the probability of the existence of adjacent nodes.
